Add study hall integration

[sharkree]

Study hall does not show up under the classes section. In addition, the schoology integration results aren't consistent-I reset schoology before 9 am today, and it didn't show my period 2 class, but now it does(~10:15).

Does the schoology api react nicely with courses that were just added? I was wondering because some issues do seem to fix themselves over time.

Might be because of this? Sometimes you do get stuff posted in the PRIME class(and Study Hall is most likely going to be the same as PRIME), so it might be better to add it in.
